JAMES MULLANEY, OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent N 0. 246,538, dated. August30, 1881.

' Application filed June18,1881. (ModeL) To all whom it may concern:

Be it known that I, JAMES MULLANEY, of the city, county, and State ofNew York, have invented certain useful Improvements in Oompound Out-Off(Jocks, of which the following is a specification.

Figure l is an elevation of my improvement, illustrating its use. Fig. 2is an elevation of the same on a larger scale, and with the pipes brokenaway. Fig. 3 is a sectional elevation of the same, taken through thelineww, Fig. 2. Fig. 4 is an end elevation of the lever-coupling, partlyin section. Fig. 5 is a sectional side elevation of the same, the handlebeing detached.

Similar letters of reference indicate corre sponding parts. Y

Tlie object of this invention is to facilitate the controlling of awater-supply from two distinct sources through the same delivery-pipes.

The invention consists in the combination, with the squaredbases of theplugs of two threeway cocks, of the coupling having a square aperture toreceive the squared ends of the plugs and a radial stem to receive thelever-handle, whereby the delivery of cold and hot water from twodistinct sources through the same delivery-pipes can be readilycontrolled, as will be hereinafter fully described.

In the accompanying drawings, A B represent two ordinary three-waycocks, which are secured to a plate, 0, a wall,or other support,

' with the bases of their plugs toward and at a little distance fromeach other. The bases of the plugs of the cocks A B are squared off tofit into the square aperture 01' socket through the coupling 1), so thatboth the said plugs can be operated at the same time and by a singlemovement of the said coupling D. Upon one side of the coupling D isformed a stem, E, which fits into an aperture or socket in the end ofthe lever-handle F, so that the said coupling can be convenientlyoperated. With the outlet-nozzles of the cooks A B are connected theends of the pipes Gr H, through which water is delivered to a basin orother desired place. With one of the inlet-nozzles of the cock A isconnected a pipe, 1, leading to a water-main, and from which a branchpipe, 1, leads to the outercompartmentofthedouble boilerJ. With theother inlet-nozzle of the cockA is connected a pipe, K, leading to atank, L, placed upon the roof of the building or in some other elevatedposition. From the pipe K a branch pipe, K, leads to the innercompartment of the double boiler J. With one of the inlet-nozzles of thethree-way cock B is connected a pipe, M, leading to the outercompartment of the double boiler J. \Vith the other nozzle of thethreeway cock B is connected a pipe, N, leading to the inner compartmentof the double boiler J.

With this construction, when the water-pressure in the main issufficient to raise the water to the desired height, the three-way cocksA B are adjusted to open a communication between the pipes I G and W H,respectively, so that the water from the main can be used. In case thepressure in the main is insufficient to raise the water to the requiredheight the two threeway cocks A B are adjusted to open a communicationbetween the pipes K G and N H, respectively, so that water can be usedirom the tank L.

With my improvement two three-way cocks, A B, can be adjusted by asingle movement of the couplingD, and without any possibility of theirbeing so adjusted as to open a communication between the wrong pipes.

Having thus fully described my invention, 1 claim as new and desire tosecure byLetters Patent The combination, with the squared bases of theplugs of two three-way cocks, A B, of the coupling D, having a radialstem, E, upon one side to receive a lever-handle, F, substantially asherein shown and described, whereby the delivery of cold and hot waterfrom two distinct sources through the same delivery-pipes can be readilycontrolled, as set forth.
